Q. No.Consider the following statements:
| I. | Myasthenia gravis is an autoimmune disorder affecting the neuromuscular junction |
| II. | Muscular dystrophy is a progressive degeneration of skeletal muscles mostly due to a genetic disorder |
| III. | Tetany is rapid spasms in muscles due to high Ca++ in body fluid. |
Which of the above statements are true?
1. I and II only
2. I and III only
3. II and III only
4. I, II and III
Which of the following is not a disorder of muscular and skeletal system?
(1) Gout
(2) Myasthenia gravis
(3) Tetany
(4) Fibrosis
Arthritis is
(1) Inflammation of joints
(2) Inflammation of forelimbs
(3) Inflammation of muscles
(4) Inflammation of ligaments
Select the correct statement regarding the specific disorder of muscular or skeletal system
1. Myasthenia gravis- Autoimmune disorder which inhibits sliding of myosin filaments
2. Gout-inflammation of joints due to extra deposition of calcium
3. Muscular dystrophy-Age related shortening of muscles
4. Osteoporosis-Decrease in bone mass and higher chances of fractures with advancing age
Which one of the following disorder of bones is characterized by microarchitectural deterioration of the bone, increased fragility, and prone to fracture?
1. Osteoarthritis
2. Gouty arthritis
3. Osteoporosis
4. Rheumatoid arthritis
Match the columns:
| Column I | Column II | ||
| (a) | Myasthenia gravis | (i) | Wild contractions for prolonged period due to ↓ Ca++ in blood |
| (b) | Tetany | (ii) | Affects neuromuscular junction and results in muscle paralysis |
| (c) | Muscular dystrophy | (iii) | Increased uric acid levels in blood and joints |
| (d) | Gout | (iv) | Degeneration of skeletal muscles |
| Options: | (a) | (b) | (c) | (d) |
| 1. | (ii) | (i) | (iv) | (iii) |
| 2. | (i) | (ii) | (iii) | (iv) |
| 3. | (iii) | (iv) | (ii) | (i) |
| 4. | (iv) | (i) | (iii) | (ii) |
Chronic auto immune disorder affecting neuro muscular junction leading to fatigue, weakening and paralysis of skeletal muscle is called as:
| 1. | Myasthenia gravis | 2. | Gout |
| 3. | Arthritis | 4. | Muscular dystrophy |
| Assertion (A): | Osteoporosis is characterised by decreased bone mass and increased chances of fractures. |
| Reason (R): | Common cause of osteoporosis is increased levels of estrogen. |
| 1. | (A) is not correct but (R) is correct. |
| 2. | Both (A) and (R) are correct and (R) is the correct explanation of (A). |
| 3. | Both (A) and (R) are correct but (R) is not the correct explanation of (A). |
| 4. | (A) is correct but (R) is not correct. |
| 1. | Muscular dystrophy | An auto immune disorder causing progressive degeneration of skeletal muscle |
| 2. | Arthritis | Inflamed joints |
| 3. | Tetany | high Ca2+ level causing rapid spasms. |
| 4. | Myasthenia gravis | Genetic disorder resulting in weakening and paralysis of skeletal muscle |
| 1. | Inflammation of joints due to accumulation of uric acid crystals |
| 2. | Weakening of bones due to decreased bone mass |
| 3. | Inflammation of joints due to cartilage degeneration |
| 4. | Weakening of bones due to low calcium level |
